Overview

The 88th New York Infantry (Three Years’ Service) was an infantry regiment organized in New York City, Brooklyn, and Jersey City for Union service during the American Civil War. Mustered in at Fort Schuyler between September 1861 and January 1862, the regiment became the 5th regiment of the famed Irish Brigade. Serving in the Army of the Potomac, the 88th New York participated in major campaigns and battles throughout the Eastern Theater, earning a reputation for steadfastness and heavy combat losses.

The regiment remained attached to Meagher’s Irish Brigade throughout its service, operating primarily with the 1st Division, 2nd Corps. It was mustered out at Alexandria, Virginia, on June 30, 1865.

Organization & Service

The 88th New York Infantry (Three Years’ Service) was recruited in New York City, Brooklyn, and Jersey City. The regiment was mustered into United States service at Fort Schuyler from September 1861 to January 1862. It departed New York for Washington, D.C., on December 16, 1861, and was attached to Meagher’s Irish Brigade, Sumner’s Division. The regiment remained with the Irish Brigade for its entire term of service.

Initially stationed near Washington, the 88th joined the Army of the Potomac’s advance to the Virginia Peninsula in March 1862, becoming part of the 1st Division, 2nd Corps. The regiment participated in the Siege of Yorktown and the Battle of Fair Oaks. During the Seven Days’ Battles, it suffered significant casualties. The 88th was engaged in the Maryland Campaign, fighting at Antietam with heavy losses. Afterward, it moved to Charlestown, West Virginia, and then by short marches to Fredericksburg, where it played a key role in the 2nd Corps’ assault and suffered severe casualties.

At Chancellorsville in spring 1863, the regiment again sustained heavy losses, leading to its consolidation into a battalion of two companies before the Battle of Gettysburg. The 88th fought in the Wheatfield at Gettysburg as part of the Irish Brigade. It continued to serve with the 2nd Corps at Bristoe Station and in the Mine Run Campaign. During the winter, enough men reenlisted to retain the regiment in the field as a veteran organization, and three new companies joined in April 1864.

Throughout the Overland Campaign from the Wilderness to Cold Harbor in 1864, the 88th New York saw continuous action. In the initial assault on Petersburg, the regiment lost heavily, including the death of Colonel Patrick Kelly, brigade commander. The regiment remained on siege duty before Petersburg until the city’s fall and was mustered out at Alexandria, Virginia, on June 30, 1865.
